基于28个省(市、自治区)1997—2018年面板数据,采用基尼系数、泰尔指数、对数离差值等综合量化分析农民收入地域差异,并运用Shapley值分解方法对要素市场扭曲下农民收入地域差异的影响因素进行分解并测度其贡献度。研究发现:农民收入地区差异呈逐年扩大趋势,虽有所波动,但是总体数值趋向于国际收入差距警戒线;不同地区要素市场扭曲对农民收入增长具有显著负向影响,而农村人力资本、农村金融发展规模、农业贸易开放度、农业规模经营水平、地区工业化水平、涉农政策调整等因素均对农民收入增长有显著正向影响;要素市场扭曲是农民收入地域差异扩大的首位因素,涉农政策调整是唯一缩小农民收入地区差异的因素,其余因素都在一定程度上扩大了农民收入的地域差异。

[Abstract]
Based on the panel data of 28 provinces (cities and autonomous regions) from 1997 to 2018, the regional differences of farmers’ income have been analyzed by using Gini coefficient, Theil index and MLD. By using Shapley value decomposition method, the factors affecting the regional differences of farmers’ income under the distortion of factor market have been decomposed and the contribution degrees of them have been measured. The study has shown that the regional difference of farmers’ income is increasing year by year. Although fluctuating, the overall value tends to reach the warning line of international income gap. The distortion of factor market in different regions has a significant negative impact on the growth of farmers’ income. The rural human capital, the scale of rural financial development, the openness of agricultural trade, the level of agricultural scale management, the level of regional industrialization and the adjustment of agricultural related policies have a significant positive impact on the growth of farmers’ income. The distortion of factor market is the first factor that causes the expansion of regional differences in farmers’ income, and the adjustment of agricultural related policies is the only factor that reduces the regional differences in farmers’ income, while the other factors have expanded the regional differences in farmers’ income to a certain extent.
